Why is the Bark Falling Off My Ash Tree?

ash blonding

Ash blonding – Notice the lighter colored bark and the bark chunks at the base of the tree

Many area residents are noticing a strange phenomenon – the bark on ash trees is falling off in pieces, giving the trunk a blond appearance. Often, there are small pieces of bark on the ground at the base of the tree. And sometimes you’ll see woodpeckers feverishly pecking at the tree trunk.

What’s going on?

What you’re seeing is one of the more visible signs of Emerald Ash Borer (EAB) infestation. Called “ash blonding”, it refers to the lighter color of the inner bark that becomes visible as the outer bark is removed by woodpeckers searching for borers under the bark.

What’s an Emerald Ash Borer?

EAB is the most devastating threat to Connecticut forests since Dutch elm disease and chestnut blight and far outpaces ash yellows as the leading cause of death for our ash trees. Ash trees across the state are dying at an alarming rate, with little sign of the infestation slowing down.

The emerald green insect itself is tiny – less than 0.5” long – but the borer (immature phase of the EAB lifecycle) does a lot of damage by feeding on the vessels that transport nutrients up and down the tree, cutting off the tree’s nutrient supply.

Emerald Ash Borer was confirmed in the Danbury area in 2016, with surrounding towns quickly following. The map below shows the prevalence of EAB across Connecticut in July of 2018.

map of towns infested with Emerald Ash Borer in Connecticut

How Can I Tell If My Ash Tree Has EAB?

There are several telltale signs of EAB infestation –

  • The tree canopy has few leaves and/or large dead areas
  • If you peel back the bark, you’ll see serpentine tunnels caused by borers feeding on the tissue
  • There are tiny D-shaped holes in the bark caused by the adult borers leaving the tree

As the infestation worsens, you may notice woodpeckers aggressively tearing at the bark. They’re trying to find the beetles (to turn them into a meal) and, in the process, are also removing pieces of the tree’s outer bark. As the lighter-colored inner bark starts to show through, the tree takes on a flecked appearance. Eventually, as more and more outer bark is removed, the tree trunk starts to look blond, rather than brown.

D-shaped hole in ash tree bark and EAB galleries

Signs of EAB infestation include D-shaped exit holes (left) and serpentine galleries under the bark (right).

What Should I Do?

First, determine whether or not you have any ash trees on your property. If you’re unsure, give us a call at 203-240-1302 – we’ll be happy to identify and inspect the trees on your property.

If you have ash trees, examine them closely for signs of EAB infestation. This should be done by a Certified Arborist because early signs often appear high in the tree canopy and are easy to miss.

Depending on the condition of the tree, you have several options –

If the tree is healthy:

  1. Preemptively cut down the tree to eliminate the chance of EAB infestation.
  2. If you’d like to save the tree, have a professional treat it with a systemic insecticide. There are no over-the-counter treatments available to homeowners in Connecticut so the insecticide must be applied by a licensed arborist.

Doing nothing is NOT an option. It’s not a case of if the tree will be infected, but when.

If the tree is infested with EAB but has no more than 30% canopy dieback:

  1. Have a licensed arborist apply a systemic insecticide to protect the tree from further damage. If the infestation is caught early enough, the tree can be treated and saved.
  2. Remove the tree to avoid spreading EAB to neighboring trees or properties.

If the tree is heavily infested or dead:

  1. Tree removal is the only option at this point.

Hint: Signs of ash blonding usually indicate that the tree is heavily infested and/or nearly dead.

Removing a tree that has died due to EAB infestation is a tricky job that can be extremely dangerous. Ash trees lose their structural integrity when they die, leaving them prone to unexpected and catastrophic failure.

This is NOT a DIY job! Only hire a Certified Arborist with the experience, skills and specialized equipment needed to safely remove a dead ash tree. And check their insurance papers to ensure that you and the tree crew are fully protected.

If you see signs of ash blonding on your trees, would like to preserve a healthy ash tree or need to have a dead ash tree removed, please call us at 203-240-1302.

How To Protect Trees From Deer Antler Rubbing

deer antler damage on tree

Deer tear off tree bark by rubbing their antlers against the trunk

What are those scrape marks on my tree?!

Deer damage to trees is the result of bucks rubbing and scraping their antlers against trees which causes significant damage to the tree’s vascular system. Deer do this to remove the velvet from their antlers and it usually occurs from early fall into winter.

Deer also rub trees during the mating season to attract females or to mark their territory, warning other males to stay away. This activity can result in broken branches and torn tree bark.

So, what can you do about it?

Keep Deer Away from Your Trees

Since deer usually return to the same location, it’s important to know how to protect your trees from deer, especially if the trees have previously been damaged.

The best thing you can do to protect your trees from deer antler rubbing is to prevent the deer from getting close to the tree trunk or branches. This can be done surrounding your trees with deer fencing or using other barriers that offer deer rub tree protection. Repellent sprays are generally not effective for deer rub problems.

>> However, sprays ARE effective at preventing deer browsing. If deer are eating your plants, give us a call at 203-240-1302 to learn how we can save your trees, shrubs and garden beds from hungry deer.

A wire or plastic mesh sleeve can be effective in preventing deer rub damage

Use Deer Fencing for Multiple Trees

Fencing is the most effective way to protect trees from deer as it keeps them away from the entire tree (including branches and leaves, which hungry deer may be tempted to eat if they can reach it). If you have many trees, surround the entire area with woven-wire fencing. However, in order to be effective, it must be at least six to eight feet tall. Deer are great jumpers and will clear vertical fences without difficulty.

Use Tree Guards to Protect Individual Trees

Another way to provide protection is to wrap the tree trunk itself with chicken wire or one of the commercially available types of plastic tree guards.

Some tree guards are made of mesh plastic netting. Others are created from a vinyl spiral that wraps around the trunk but still allows it to grow naturally. They are usually available in rolls and can be cut to the required length. Because they can be cut to size, these types of tree guards work well on larger trees, as well as small ones.

Plastic tubes or pipes that have been cut down one side (lengthwise) can also be fitted around the trunks of trees in an effort to protect trees from deer. This works best for smaller diameter trees. Be sure to choose a plastic that’s white or light in color so it does not produce heat against the tree trunk from the sun.

These wraps and pipes can also protect the tree trunk from sunscald caused by intense sun reflecting off the snow, which has been known to blister or crack the bark.

American Chestnut Blight: An Update & Next Steps

chestnut tree foliage

Until the 1930s, America’s eastern forests were dominated by the American chestnuts (Castanea dentata). One in four trees was a chestnut – there were millions of chestnut trees covering the landscape. The majestic hardwood trees reached up to 100 feet tall and were favored by Native Americans and early settlers for their fine timber and edible nuts. The nuts were also essential to wildlife.

Then the unthinkable happened.

Chestnut blight, a deadly fungal disease introduced to the United States from Asia in the early 1900s, destroyed our chestnut forests and threatened the very existence of these important trees.

Since then, tree breeders and researchers have worked to find blight-resistant varieties to bring American chestnuts back to our landscapes and forests. And, after years of research and millions of dollars of investment, it looks like they may be succeeding!

American Chestnut Restoration

Organizations such as The American Chestnut Foundation (TACF) are on the forefront of research dedicated to restoring these important North American trees to our forests. Over 25 years ago they created the American Chestnut Research and Restoration Project, an effort spearheaded by researchers at State University of New York College of Environmental Science and Forestry. In that time, lots of hopeful discoveries have been made.

Many blight-resistant American chestnut varieties have been found — TACF calls them “Restoration Chestnuts”. Some were collected in the wild, others bred with blight resistant Chinese chestnuts, and still others genetically engineered with blight-resistant genes.

All of these varieties have brought us closer to having truly disease resistant American chestnuts, but researchers have taken the effort one step further. They realized a more intensive, collaborative effort was needed to repopulate our forests with these ecologically vital trees.

Ten Thousand Chestnut Challenge

In 2014, TACF launched a crowd-funded campaign called the “Ten Thousand Chestnut Challenge”. The challenge was to plant 10,000 chestnuts in eastern research orchards where resistant American chestnuts could be bred for disease resistance and diversity.

If successful, they will select disease-resistant chestnuts able to grow in many regions across eastern North America for forest repopulation.

Donors gave $101,911 to support the campaign, and over the last three years thousands of trees have been planted to meet the 10,000 chestnut goal.

Chestnut Blight Restoration Progress

So, what progress have they made?

The American Chestnut Foundation has helped plant over 1.8 million blight-resistant Restoration Chestnut seedlings in eight states since 2009. These have been planted in both forests as well as public and home landscapes. Highly blight-resistant American chestnut varieties from the Ten Thousand Chestnut Challenge also show great promise and are being planted and monitored.

American Chestnuts for Homeowners

So what does this mean for you, the homeowner?

These beautiful blight-resistant chestnut trees are great for wooded yards and edible landscapes, but everyday landscape nurseries don’t sell them, yet. The best way to get your own blight-resistant Restoration Chestnut is to join The American Chestnut Foundation. Members are sometimes offered these trees for home planting, and you can become part of the restoration process!

 

 

Facts About Gypsy Moth in Connecticut & How To Control Them

Gypsy Moth Attacking Your Trees?

Call Today For a Complimentary Inspection & Treatment Estimate

203-240-1302

 
We’ve been relatively lucky so far in the Danbury area and Fairfield County – most of the recent gypsy moth infestations and the resulting defoliation of trees took place in eastern Connecticut. But this year could turn out to be much worse for us.

What Is a Gypsy Moth?

The gypsy moth is a small nondescript moth that’s usually active for a short period of time in mid to late July. It’s not the moth we need to worry about though – it’s the caterpillars.

You’ve probably seen gypsy moth caterpillars before. They’re hairy critters with a double row of blue and red dots down their back. And they hang from trees by thin silk threads, getting in your hair and on your clothes whenever you walk under a tree. Ugh.

The female gypsy moth lays eggs in a mass of up to 1000 eggs that hatch into caterpillars in late April to early May. The caterpillars climb up into nearby trees and start eating – and eating and eating …

Their favorite plant to eat seems to be oak trees, although they’ll also munch their way through apple, birch, poplar and willow. They’ll generally leave conifers alone, except during a heavy outbreak.

Gypsy Moth Damage in Connecticut

In years when we have a bad gypsy moth outbreak in Connecticut, nearly all the trees in the area will be completely defoliated. For example, in 1981 over 1.5 million acres of trees lost all their leaves.

More recently, we’ve seen an increase in the number and severity of gypsy moth outbreaks in Connecticut. 2015 saw over 180,000 acres defoliated and 2016 was even worse, with 204,167 acres affected. What’s even more concerning is that the latest outbreak saw many trees completely stripped of leaves, including trees that normally aren’t targeted by the gypsy moth, such as spruce, pine and hemlock. 

A healthy tree can usually survive being defoliated once in a season. It’ll generally grow back most of its leaves before fall, although some of the tree may look a little sparse. But older or stressed trees (such as during a drought) will have difficulty regenerating leaves, may become vulnerable to attack by other insects or disease, and may not have the stored energy needed to survive through the winter.

After two or three consecutive years of defoliation, even the healthiest tree will probably die. 

Why Has Gypsy Moth Damage Been Worse Lately?

For many years, the gypsy moth population in Connecticut has been controlled by a fungus called Entomophaga maimaiga. It’s harmless to humans and other animals (including pollinators and beneficial insects) but it’s deadly for the gypsy moth caterpillar.

The problem is that the fungus needs a certain amount of moisture from early season rains in May and June in order to be activated. In dry springs, like the last two years, the fungus can’t grow and spread fast enough to infect a significant number of caterpillars. As a result, we end up with a caterpillar outbreak.

How To Control Gypsy Moths

Rather than waiting to see what may happen with weather in spring and hoping that the maimaiga fungus will bring down the gypsy moth population, most homeowners choose to proactively treat their trees to control gypsy moth.

There are two ways to control the spread and amount of damage caused by gypsy moths –

  • preventive treatments (such as removing egg masses) and
  • directly targeting the caterpillars with a variety of insecticides.

Targeting adults (after the caterpillar stage) and pupa (before the caterpillar emerges) generally isn’t effective.

Preventive Treatments for Gypsy Moth

Prevention focuses on two things – preventing eggs from hatching and preventing caterpillars from reaching the tree canopy where they feed.

One option is to manually remove egg masses by scraping them off surfaces and destroying them (such as by drowning them in soapy water – just leaving them on the ground won’t kill them). The problem with this is that egg masses can be high up in the trees where you can’t reach them, they’re hard to see, and they can be on just about any surface, including your car! Plus, even if you eliminated all egg masses on your own property, young caterpillars can be blown in from neighboring properties.

You can also spray trees and other surfaces with a horticultural oil or insecticidal soap to completely soak egg masses. This prevents them from hatching. Be sure to do it before eggs start hatching in late April! Because you need to cover all egg masses, this is something best done by an arborist who has the spray equipment to reach all areas.

To prevent caterpillars from climbing tree trunks, you can place a band around the trunk to trap caterpillars as they climb. This is usually a folded piece of burlap or a sticky band. You’ll have to kill the trapped caterpillars so this isn’t something for the squeamish person!

Chemical & Biological Treatments for Gypsy Moth

These types of treatments are best applied by a CT Licensed Arborist who has the spray or tree injection equipment necessary to get full coverage of all trees on your property. And some treatments can only be applied by a Licensed Arborist who’s licensed by the CT Department of Energy and Environmental Protection (DEEP).

The best results are achieved after the caterpillars have hatched but are still relatively young – some time in mid-May to mid-June. It usually only requires one treatment, although if there’s a heavy outbreak or your neighbor hasn’t treated their trees, you may need a second treatment.

How Barts Controls Gypsy Moth

We prefer to avoid spraying when possible (it can be hard to control exactly where the spray goes when spraying large trees and some residents have health and safety concerns about insecticidal sprays).

Instead, we use TREE-äge® from Arborjet – a highly effective insecticide with a long residual (meaning that it stays active in the tree for a couple of years) that’s injected directly into the tree trunk. We find that this systemic approach (meaning that the treatment is dispersed throughout the entire tree, not just on the surface or on some parts) is much more effective than foliar sprays.

And, because it’s injected into the tree, there’s no risk of chemical exposure to you, your family or pets on your property.

Plus, your trees only need treatment every two years instead of annually.

Although you can treat with TREE-äge at any time during the growing season, September is the ideal time to do a tree injection to protect your trees from gypsy moths. This means that the trees are fully protected going into next year’s growing season.

Call us today at 203-240-1302 to set up a complimentary gypsy moth consultation. We’ll take a look at your trees, discuss your treatment preferences and recommend the best option for controlling gypsy moth on your property.

How To Prevent Winter Deer Damage

stop winter deer damage to treesIf there are deer in your neighborhood then they’ve probably stopped by your property to feed. As deer populations increase in Connecticut, more and more homeowners are faced with the problem of trying to keep them away from landscape plants, especially in winter when there’s little other food available to hungry deer.

An adult deer eats between 6 to 7 pounds of plant material every day. With that kind of voracious appetite, it won’t take long for them to totally decimate the plantings on your property.

Deer also carry ticks that spread Lyme disease and other tick-borne infections. Although deer may look cute, you definitely don’t want them hanging around your home!

So what can you do to keep deer away?

Below are the most effective ways to prevent deer browsing. However, if winter weather is harsh enough and food becomes scarce, deer will munch on just about anything. This includes normally “deer-resistant” plants and shrubs, as well as some plants that have been sprayed with repellents that are highly effective under normal conditions.

Effective Ways to Prevent Deer Damage

Spray Repellents

For most homeowners, the easiest and most economical approach to keeping deer away is a spray repellent program starting in the fall. This spray is innocuous to plants and shrubs while smelling and/or tasting bad to the deer.

Here in Connecticut, deer repellent sprays should be applied September through December when temperatures are above freezing. Application earlier in the browsing cycle (September and October) leads to much better results.

There are two types of deer repellents, contact repellents and area repellents. Contact repellents are applied directly to plants, causing them to taste bad (this is what we use at Barts). Area repellents are placed in a problem area and repel by their foul odor but we haven’t found these to be as effective.

Spray repellents should be applied on a dry day with temperatures above freezing. We treat young trees completely and older trees may be treated only on their new growth and buds. Treat to a height 6 feet above the maximum expected snow depth. Deer browse from the top down.

Home-remedy deer repellents are questionable at best. These include small, fine-mesh bags of human hair and bar soap hung from branches of trees, among others. The only truly effective home remedy I’ve seen is a 100 lb dog in your yard. Deer don’t like things that remind them of wolves and they’ll generally stay clear.

At Barts Tree Service we spray “Deer Free Winter Armor” to protect your landscape from deer. This is a white pepper based product so as you can imagine it doesn’t taste good at all. The product lasts 6 months and is made right here in the USA. One of the best features of this product is that it dries clear, whereas most of the other deer repellent sprays on the market have a green dye which can stain your house, walkway or other infrastructure.

>> GET A DEER SPRAY ESTIMATE

Deer Fencing

Another option is to put up deer fencing around all plants that you want to protect. Keep in mind that this fencing must be 8 feet tall – anything shorter and deer can jump over it! If you have a few specimen trees or large flower beds, this can be a good choice as there’s no need to spray once the fence is up. The downside is the work involved in actually putting up the fence and the space needed to store it during the warmer months.

Electric fences also can be used. Electric fences should be of triple-galvanized, high-tensile, 13.5-gauge wire carrying a current of 35 milliamps and 3,000 to 4,500 volts. Several configurations of electric fences are used: vertical five-, seven-, or nine-wire; slanted seven-wire; single strand; and others. When using a single strand electric fence it helps the deer to see that the wire is there if you mark it with cloth strips, tape or something similar. Otherwise, the deer may not see it in time and go right through it.

Wrapping in Burlap

If you only have smaller shrubs to protect, you may want to simply wrap them in burlap. Not only does this protect them from grazing deer, but it protects the shrubs from drying out in the cold winter winds. You can learn more about this in our article on preventing winter browning in evergreens.

Emerald Ash Borer Treatment For Connecticut

Emerald Ash Borer treatment to save ash trees

Save Your Ash Trees Before It’s Too Late

By the time you see obvious signs of infestation in your ash tree, Emerald Ash Borer (EAB) has been there for years and it’s usually too late to save the tree. That’s why preventive treatment is so important.

EAB was confirmed in the Danbury area in 2017, putting all local ash trees at risk from this devastating pest. It’s no longer a matter of if ash trees in our area will be infected, but when it will happen.

 

Don’t Take Chances With Your Ash Trees

Call us for your free ash tree inspection and EAB treatment plan.

Call 203-240-1302 Today

 

The brief video below explains how ash trees can be saved from EAB and what happens when they aren’t treated with a preventive insecticide.

What To Do If You Have Ash Trees

The best thing you can do right away is to assess how EAB has or will impact your property.

Ask yourself the following questions:

  1. Do I have ash trees on my property?
  2. Are they in good health?
  3. Do I want to save them?

If you answered “yes” to all three questions then it’s time to get a thorough EAB inspection.

Our licensed Arborists can determine whether or not EAB is present in your ash trees (they’ll climb into your tree because it’s not easy to see Emerald Ash Borers from the ground).

If there are no signs of EAB or only a light infestation (up to 30-40% of the tree), then your ash trees are a candidate for EAB prevention and treatment.

How To Protect Your Trees From Emerald Ash Borer

Arborject TreeAge

Arborjet TreeAge insecticide is injected directly into the tree – no spraying!

We’ve been treating ash trees for Emerald Ash Borer for years, using highly effective Arborjet tree injections with the industry-leading TreeAge insecticide. This product has a 90% efficacy in killing feeding insects and larva and is still effective even if a tree is up to 30%-40% infested with EAB.

TreeAge insecticide has a 2-year residual time frame so Emerald Ash Borer injections are only needed every two years.

And because it’s injected directly into the tree, there’s no spraying involved so you don’t have to worry about air-borne insecticide affecting your family, pets, or neighbors.

So if you have ash trees, give us a call to have one of the Barts Tree Service Licensed Arborists assess your ash trees for EAB. And if you’re not sure what kinds of trees you have, we’ll happily take a look and identify them for you.

Barts Finds Emerald Ash Borer in Danbury

Barts Tree Service finds EAB in Danbury

Tree-killing pest found in Danbury

This article first appeared in the Danbury NewsTimes.

DANBURY — Four years after it was discovered in Connecticut, an invasive insect that is killing ash trees across the country has been found in Danbury.

A contractor working on Maplewood Drive this week found an ash tree infected with the emerald ash borer, a small, green non-native species of beetle so destructive that it is expected to all but wipe out ash trees in the Northeast in as little as a decade.

City and state officials said Friday this is the first report of an ash borer infestation in the city, but they were not surprised to hear it.

“This is not a new infestation,” said Katherine Dugas, a research assistant with the Connecticut Agricultural Experiment Station, or CAES. “What we’re seeing is confirmation, rather than an expansion.”

The insect showed up in Connecticut in 2012, a decade after its first appearance in Michigan. It is thought to have migrated from Asia.

Because the ash borer has established itself in at least 26 states, officials say, eradication is no longer considered possible. Instead, authorities have focused on slowing or preventing the spread of the insect into new areas by, for example, banning the moving of firewood.

Still, experts say, nearly every ash tree in Connecticut, and probably the entire northeast and eastern Canada, is destined to die.

Matt Bartelme, the contractor who spotted the infested tree near the New York state border this week, said Danbury’s ash trees are probably “doomed.”

“Now that we know that is in our area, all the ash trees are at a high risk of dying unless they’re chemically treated,” he said.

Other towns already affected include Newtown, New Milford, Sherman, Southbury and Bridgewater.

“It’s been around us,” Bartelme said. “It was just a matter of time until it got here.”

Gale Ridge, a CAES assistant agricultural scientist, said any trees within a 15-mile radius could be considered in danger.

Female ash borers lay their eggs under the bark of ash trees. When the eggs hatch, the larvae feed on the inner layers of the tree bark, cutting off the tree’s circulatory system. Nutrients then can’t reach the top of the tree, Bartelme said, so the crown and the top branches eventually die.

Trees tend to die within two to three years after becoming infested, but some last as long as eight years.

Other signs of infestation include D-shaped holes on the bark, horizontal tracks on the inner surface of the bark and unusual numbers of holes drilled by woodpeckers, for which ash borers are a favorite food.

Bartelme, who owns Barts Tree Service, said one of the best treatments is an insecticide known by the brand name Tree-äge, which is injected into the tree.

Another way of monitoring the spread of the ash borer is by noting the presence of a stingless wasp known as the smokey winged beetle bandit, which preys on the borer, Ridge said.

“We have research going on that is very promising to bring the population down,” she said.

Chris Martin, head of the state Department of Energy and Environmental Protection’s forestry division, said the insect could be active for up to five years before anyone notices.

“It’s very probable that the population has just grown and only now people are starting to notice that their ash trees are dying,” Martin said.

Infected trees should not be used as firewood because any larva or eggs underneath the bark could survive in cut wood long enough to find living hosts.

Q&A: Can I Stop Emerald Ash Borers From Killing My Ash Trees?

Emerald Ash Borer

Emerald Ash Borer

Q: I heard that Emerald Ash Borer (EAB) is now threatening our local ash trees. Is there anything I can do to save my trees?

Emerald Ash Borer was first found in Prospect, Connecticut in 2012 and since then has spread to a large part of the state, infesting and killing ash trees as it goes.

It’s very difficult to see the early signs of EAB infestation since the insects lay eggs in the top of the tree first and then slowly move down over the next couple of years. Usually by the time you can see visible signs of infestation from the ground, EAB has been there for years.

But don’t panic – there’s still time to try to save your ash trees.

Arborject TreeAge

Arborjet TreeAge insecticide is injected directly into the tree – no spraying!

We’ve been performing Arborjet tree injections using the industry leading TreeAge insecticide, which has a 90% efficacy in killing feeding insects and larva. This product is still effective even if a tree is infested up to 30%-40%.

TreeAge insecticide has a 2-year residual time frame so injections are required only every two years. And because it’s injected directly into the tree there’s no spraying involved so you don’t have to worry about air-borne insecticide affecting your yard, pets, or family.

So if you have ash trees, give us a call to have Barts Tree Service Licensed Arborists come and assess your ash trees for EAB. And if you’re not sure what kinds of trees you have, we’ll happily take a look and identify them for you.

Don’t wait until your ash trees are dying – treat them quickly and eliminate EAB.

Preventing Winter Rodent Damage on Young Trees

Winter rodent damage to bark of a young tree

Winter rodent damage to the bark of a young tree

Mice, voles, rabbits and rodents can cause damage to young trees, saplings and shrubs during the winter months by feeding on bark, twigs, buds and foliage.

As snow accumulates around tree trunks and lower branches, it provides a great environment for little critters to tunnel around tree trunks. By tunneling under the snow, they can create a protected habitrail network for feeding, especially when deep snow on the ground is persistent.

This feeding can create small nibbling wounds in the bark and deeper layers of the tree which allow fungal and parasitic attacks come spring. In some cases, the damage can be severe enough where the trunk is girdled (eaten away entirely around the circumference) and cuts off vascular flow, killing the tree or shrub.

If the snow has a nice hard crust you will also see tree damage two or three feet off the ground – just above the snow level. Since rabbits and the like can stay on top of the snow pack while foraging, they have access to bark higher up the tree.

How to Prevent Winter Rodent Damage

Before the snow starts flying, wrap ¼ inch wire mesh around the bottom 24 inches of the tree. Be sure to sink the mesh 2 inches into the ground so the critters can’t get under it. Ensure the mesh is not too snug around the trunk and consider removing it each spring. There are also plastic tree guards that work well.

During the winter, shovel snow from around your small trees so as to eliminate the rodent habitrail feeding opportunity. This also allows predators, especially owls and hawks, to have a clear sight line to these rodents if they are going for a snack so it will naturally reduce the likelihood of rodent damage.

Emerald Ash Borer Update for Connecticut

Emerald Ash Borer

Emerald Ash Borer

We just attended a great Emerald Ash Borer (EAB) workshop put on by Connecticut Tree Protective Association (CTPA) and the town of Southbury, CT where we met with our state experts and entomologists to review the latest information and best practices for dealing with EAB. Then we had a little field trip and visited local infested sites where we peeled the bark off to see the EAB larva.

About Emerald Ash Borer

EAB infests only ash trees. Ash makes up approximately 4% of Connecticut’s trees and up to 20% in urban areas. An EAB infestation can kill a tree in 3-5 years. In some areas where ash yellows disease is also present this can result in a huge increase the rate of mortality for ash trees.

Emerald Ash Borer has destroyed over 100 million ash trees so far and over the next several years will threaten every ash tree in the Connecticut area.

Emerald Ash Borer was first detected in Prospect, CT July 16th of 2012 and has spread quickly. Although EAB generally travels only ½ a mile per year, it is easily transported on logs and firewood from infested trees. With people moving wood around (e.g., taking firewood to your summer camp, removing dead trees from your yard) the spread of EAB is usually greatly accelerated.

EAB Firewood Quarantines in Connecticut

In efforts to limit the movement of infested ash wood, the DEEP implemented a quarantine for New Haven County so logs and/or firewood can not be transported outside of the county without meeting certain criteria (kiln dried, debarked logs, etc.) and obtaining permits. Because of recent EAB findings, the quarantine has been expanded to include New Haven, Fairfield, Litchfield and Hartford Counties.

What Connecticut is Doing to Combat EAB

Parasitic Wasps – DEEP has released parasitic wasps as a biological control at four locations in CT. These wasps attack only the EAB and can kill them quite effectively  although it is still too early to know the impacts on the EAB population in Connecticut.

Increased Enforcement – DEEP has submitted changes to update the quarantine laws so that local police can implement fines on the spot for people caught moving wood, whereas now they can only write a promise to appear for court. Hopefully, this will increase police enforcement. Additionally DEEP has started to implement spot checks with DOT on certain main access ways.

EAB Traps – You might see purple square traps hanging out of trees along roadsides; we call them “Barney Traps” for the color. These traps help DEEP detect and track the EAB population as it migrates across Connecticut.

How You Can Manage EAB

The keys to managing EAB are to fully understand your options and to take a proactive approach. Now that EAB is just starting to be detected in our area, we’re doing our best to provide you with education on EAB best practices. This will help you make informed decisions that fit your budget and will benefit your trees.

The best thing you can do right away is to assess how EAB has or will impact your property. Ask yourself the following questions:

  1. Do I have any ash trees? How many do I have?
  2. What’s the condition of my ash trees?
  3. What are the associated risks?
  4. Should my ash trees be treated or should I plan for removal?

There are some treatments to help prevent EAB damage (we use a special systemic tree injection process) but if you have a lot of ash trees, you may want to proactively remove some of them instead. We’re happy to help you figure out the best options.
